摘要

通过使用光控取向技术和多种成分的手性液晶，观察到了液晶系统在外电场激发下的微观周期结构。这种周期结构的形貌强烈依赖于表面取向结构、手性掺杂浓度以及驱动电场属性。特别是随着掺杂手性浓度的增加，微结构的周期方向发生大幅度的改变。本文的工作是对传统的非手性液晶光控领域的一个扩展，可望实现光场、电场和浓度场等多重调节的液晶光栅，其周期取向能够大角度调节。这种可调光栅有望在图像处理、光开关、光束调制等其他光通信领域发挥重要的作用。

Abstract

By using the photoalignment technique and the chiral liquid crystal with various components

the micro periodic structure of the liquid crystal system excited by the external electric field is observed. The morphology of the periodic structure strongly depends on the structure of the surface orientation

the concentration of the chiral doping and the properties of the driving electric field. Especially

with the increase of doping concentration

the periodic direction of microstructure changes greatly. The work of this paper is an extension of the traditional optical control field of the achiral liquid crystal. It is expected to realize the multiple adjustment of the light field

electric field and concentration field of the liquid crystal grating

and its periodic orientation can be adjusted at a large angle. The tunable grating is expected to play an important role in image processing

optical switch

beam modulation and other optical communication fields.
